METHOD FOR DETECTING SUBSTANTIALLY PERIODIC SERIES OF BURSTS OF SUBSTANTIALLY SINUSOIDAL SIGNALS

摘要

The present invention relates to a method for detecting substantially periodic series of bursts of substantially sinusoidal signals, in particular but not exclusively series of bursts of signals transmitted in a recurring fashion (by pingers, for example), said method enabling the quick and reliable detection of such signals in the presence of high interference noise. Said method comprises the following steps: slightly delayed processing of the received signal; performing spectral analysis and time integration; and presenting the results as a two-dimensional image of consecutive recurrences of bursts in accordance with the time slots of the received signals.
